Abstract

An electronic display device includes: a chassis including a plurality of mounting elements and an antenna, a power supply, a controller, a media player, a gateway, and a terminal; and a display panel comprising a plurality of display modules mounted to the mounting elements, wherein each display module includes a video display on a front surface of the display module and is positioned relative to the chassis using one or more locating pins located on a back surface of the display module that cooperate with one or more receiving holes in a front surface of the mounting elements, is magnetically secured to the chassis, and is locked in place relative to each respective mounting element using a locking mechanism, such that each individual display module may be secured or removed from the chassis independently; wherein the controller causes the media player to display media content on the display panel.

The invention claimed is: 
     
       1. An electronic display device comprising:
 a chassis including a plurality of mounting elements and an antenna, a power supply, a controller, a media player, a gateway, and a terminal; and 
 a display panel comprising a plurality of display modules mounted to the mounting elements, wherein each display module includes a video display on a front surface of the display module and is positioned relative to the chassis using one or more locating pins located on a back surface of the display module that cooperate with one or more receiving holes in a front surface of the mounting elements, is magnetically secured to the chassis, and is locked in place relative to each respective mounting element using a locking mechanism, such that each individual display module may be secured or removed from the chassis independently; 
 wherein the controller causes the media player to display media content on the display panel. 
 
     
     
       2. The electronic display device of  claim 1 , wherein each display module includes an LED video display. 
     
     
       3. The electronic display device of  claim 1 , wherein at least the front surface of each display module is covered by a silicone covering. 
     
     
       4. The electronic display device of  claim 1 , wherein the chassis is secured to a rear door of a semi-tractor trailer. 
     
     
       5. The electronic display device of  claim 4 , wherein the electronic display device includes two chassis and two display panels, each secured to a rear door of a semi-tractor trailer. 
     
     
       6. The electronic display device of  claim 1 , wherein the chassis includes a channel that accommodates one or more vertical locking bars that span a height of the chassis. 
     
     
       7. The electronic display device of  claim 1 , wherein the media content displayed on the display panel is updated in response to geolocation data received through the antenna. 
     
     
       8. An electronic display device comprising:
 a first chassis and a second chassis, each mounted to a respective first and second rear door of a semi-tractor trailer, wherein each chassis includes a plurality of mounting elements and at least one of the first chassis and the second chassis includes an antenna, a power supply, a controller, a media player, a gateway, and a terminal, further wherein each chassis includes a channel that accommodates one or more vertical locking bars that span a height of the chassis; and 
 a first display panel and a second display panel, each comprising a plurality of display modules mounted to the mounting elements of the first chassis and the second chassis, wherein each display module includes a video display on a front surface of the display module and is positioned relative to the chassis using one or more locating pins located on a back surface of the display module that cooperate with one or more receiving holes in a front surface of the mounting elements, is magnetically secured to the chassis, and is locked in place relative to each respective mounting element using a locking mechanism, such that each individual display module may be secured or removed from the chassis independently, further wherein at least the front surface of each display module is covered by a silicone covering; 
 wherein the controller causes the media player to display media content on the first display panel and second display panel. 
 
     
     
       9. The electronic display device of  claim 8 , wherein the media content displayed on the first display panel and second display panel is updated in response to geolocation data received through the antenna.
